The D12S1R8 is the latest offering in the DXP family which was developed to address the ever-growing demands of increased current and power densities in networking applications while providing maximum flexibility for system configuration, its benefits can easily be applied to other applications transcending various market segments. The DXP family, containing all necessary power components and boasting of a USABLE ( C, LFM) current density of 6A/in 2 and a power density of up to 216W/in 3, is a building block for a new open Digital Power Architecture developed to work with either digital or analog controllers. Measured at. Wx1. Lx.48 H and rated at A of output current, the D12S1R8 is designed to operate with an input voltage from 7V to 13.2V and provide an output voltage adjustable from.8v to 1.8V in digitally defined step resolution of 1.62mV. Multiple D12S1R8 can be used in parallel to serve applications where output currents are in excess of A with limitation imposed only by the control circuit, analog or digital. Designed for superior price/performance, the D12S1R8 can provide 1.8V and A full load in ambient temperature up to C with LFM airflow.

6 TEST CONFIGURATIONS DESIGN CONSIDERATIONS Vo GND 6uF*3 Oscon 3uF MLCC SCOPE Resistive Load The power module should be connected to a low ac-impedance input source. Highly inductive source impedances can affect the stability of the module. An input capacitance must be placed close to the modules input pins to filter ripple current and ensure module stability in the presence of inductive traces that supply the input voltage to the module. Figure 11: Peak-peak output ripple & noise and startup transient measurement test setup Note: 3pcs 6μF OSCON and 3μF MLCC capacitor in the module output. Scope measurement should be made by using a BNC connector. VI Vo GND Safety Considerations For safety-agency approval the power module must be installed in compliance with the spacing and separation requirements of the end-use safety agency standards. For the converter output to be considered meeting the requirements of safety extra-low voltage (SELV), the input must meet SELV requirements. The power module has extra-low voltage (ELV) outputs when all inputs are ELV. The input to these units is to be provided with a maximum 1A time-delay fuse in the ungrounded lead. FEATURES DESCRIPTIONS Figure 12: Output voltage and efficiency measurement test setup Note: All measurements are taken at the module terminals. When the module is not soldered (via socket), place Kelvin connections at module terminals to avoid measurement errors due to contact resistance. Vo Io ( ) % Vi Ii Over-Current Protection To provide protection in an output over load fault condition, the unit is equipped with internal over-current protection. When the over-current protection is triggered, the unit will be shutdown and restart by input or OUTEN on/off. The units operate normally once the fault condition is removed. Over-Temperature Protection Input SCOPE Cin Cout 16V/uF * 4pcs Aluminum Vo To provide additional over-temperature protection in a fault condition, the unit is equipped with a latching thermal shutdown circuit. The shutdown circuit engages when the temperature of monitored component exceeds approximately 1. The shutdown unit will restart by input or OUTEN on/off while the temperature lower than 12C. Figure 13: Peak-peak Input ripple & noise measurement test setup Note: 4pcs 1,μF Aluminum in the module input. Scope measurement should be made by using a BNC connector. 6

7 THERMAL CONSIDERATIONS Thermal management is an important part of the system design. To ensure proper, reliable operation, sufficient cooling of the power module is needed over the entire temperature range of the module. cooling is usually the dominant mode of heat transfer. Thermal De-rating The module s maximum hot spot temperature is +113 C. To enhance system reliability, the power module should always be operated below the maximum operating temperature. If the temperature exceeds the maximum module temperature, reliability of the unit may be affected. Hence, the choice of equipment to characterize the thermal performance of the power module is a wind tunnel. Thermal Testing Setup Delta s DC/DC power modules are characterized in heated wind tunnels that simulate the thermal environments encountered in most electronics equipment. The following figures show the wind tunnel characterization setup. The power module is mounted on Primarion test board and is horizontally positioned within the wind tunnel.
